69 Jack questions

Re: 69 Jack questions

Joe,
There is no question, that I personally removed all these jacks from Corvettes. I can only assume that they were original to the cars. I cannot even tell you with any certainty exactly what year cars I removed them from. There have been quite a few over the last 10 years or so. I think some input from the members who own and drive the 76-80 cars (particularly original owner cars).

I don't doubt that they were removed from cars of the year models described and that they may be original to those cars. I'm simply saying that if they were original to those cars, then I would have to believe the factory installed jacks that were other than the part number seen in the AIM, i.e. 3958710.

The only other possibilities are that the specifications for the 3958710 were drastically revised at some point or that the specifications for the 3958710 allowed for more than one design. I consider both of those possibilities highly unlikely.

Joe,
Understood and agreed with. I would be very surprised that this has not been "caught" before now by someone in the organization. Possibly it has and I have just not seen it in any of my material, or I do not have it. Seems like more investigation may be order, maybe a Restorer article??
Do you find the jack numbers in the Corvette GM parts books, as well as in the AIM?

Re: 69 Jack questions

Thanks guys
i was digging thru my stash of jacks this afternoon and i found and saw the differences everybody pointed out. I have several jacks one is the early 69 style dated 8 J with the small foot. And 2 more 69 jacks with the larger foot pad one is dated 9 H or G cannot remember and the other is dated 9 K and both of these have the A stamped on the top as some one pointed out and one jack dated 0 G early 71 car maybe with no A on the top. I would take pictures and post them for everybody to see but i do not know how to post pics tried and nothing came up. If anybody needs pics i will see if i can get my girlfriend to do it i am not to savy with the computer just basics.

I used both as well as other references. However, I'm not sure any of them are correct since everything shows the 3958701 being used at least through 1979 and, in some cases, later than 1979. I'd say that based on "empirical evidence", that can't be how it was.
